Review: O-Chain's Active Spider Adds Suppleness & Silence
Interesting theory here on kickback vs small inputs from riders... but I do have three questions: -where is this 1.8 m/s suspension speed coming from? Has anybody with a telemetry setup found/published realistic values for vertical wheel speeds during bumps or is this a guess? -the statement "unlikely to occur at those bike paces" seems misleading as you tend to coast in a gear that allows good pedaling cadence for when you need to sprint- albeit the kickback is theoretically lower in high gears, but also you would expect the speed the suspension moves is higher too, so analyzing a few design cases is maybe the best way to think of it. -can we rule out a third, even simpler hypothesis that the chain slapping around that mad produces noticeable feedback? Of course it could also be any combination of these three distinct phenomena with varying importance. I do agree that placing the blame on the clutches makes little sense, too.

Rimpact Launches Updated Original & Pro Inserts
@mrift04: I have both Cuschore and Rimpact Original, they are both great for different reasons. Cushcore for all-out performance on the DH bike. Rimpact for the Enduro bike. Lighter (100g vs 260g), much easier to install, cheaper, still works pretty well. P.S. Rimpact comes with Valve stems, and they're better than Cuschore's (4 side holes instead of 2).

Rimpact Launches Updated Original & Pro Inserts
To be fair to Rimpact, I have DH Casing/Cushcore on my DH bike and DD Casing/Rimpact Original on my enduro bike (same wheelset), and the Rimpact is massively easier to install, a much bigger difference than what you would expect between DH and DD casings.

Short or Long-Travel: Which Is The Best All-Round MTB?
@bncuthbert: you are technically correct. The best kind of correct

Short or Long-Travel: Which Is The Best All-Round MTB?
You can't say whether something is statistically significant or not unless you do the math to find the significance level, that's misleading. Lets do the math. You really need to decide and specify the confidence level first, so lets start with an industry standard 95%. A quick student's t-test yields a mean of 66.38 and 67.02 and a variance of 0.622 and 0.210, respectively. Put this together and we have a t-value of 1.57. Given the total of 8 degrees of freedom, this gives a p-value of ~15%, which means we are ~85% sure the mean test times of the bikes are different. This however is not enough to meet our confidence level so we can now say that the difference is statistically insignificant.

Koroyd Wins Patent Infringement Lawsuit Against Burton Helmets With WaveCel
@fabwizard: Combing a pda with a phone *was* the innovation, and was hugely influential, don't pretend thats not massively important. There were plenty of precursors to smartphones- but the iphone brought a mass market, multi-touch touchscreen phone to market first and it was big, and gave apple an advantage still seen today. Copyright is not the same as a patent- copyright protection is automatic, registering just makes it easily traceable as evidence should you take someone to court, and they don't cover ideas like a patent does, copyrights cover expressions of an idea in the form of a creative work. Also, the case of pirate bay is about the pioneer of an industry doing things illegally, making netflix the pioneer of doing it legitimately, a pretty huge difference. Whenever you think "streaming" most people immediately think of netflix and sort of brand recognition is a huge advantage right there. What you are saying about crocs is demonstrably false. Clogs are 54% of their revenue, as stated in their Q3 earnings report, which is public as they are a public company. And that's after they acquired an entire second brand, HEYDUDE shoes, which makes up 27% of their revenue. Its also relatively unimportant anyways, as the point is that crocs became hugely profitable by being the pioneer of that style product, thus demonstrating the incentive to pioneer new styles of products exists. At this point I have no idea what point you are even trying to argue here. What markets and products are immune to the pioneer advantage? What evidence is there that pioneer advantage decreases as technology advances?

Koroyd Wins Patent Infringement Lawsuit Against Burton Helmets With WaveCel
@fabwizard: Tesla quite famously made all of its patents available for use to anyone, for Apple I am referring to their pioneering of the Smartphone, of which there are many competitors, and pirate bay was shut down for copyright infringement, which is not the same as patent infringement. Crocs started out building a production run of 200 shoes and now has a revenue of $2B, even though they are losing market share to imitators they still have definitely demonstrated that there is incentive to develop new products even if there are imitators and you lose market share eventually to them. The point is that patent protection is not the *only* incentive to develop products, nor are patents perfect at protecting IP anyways, it's not so black and white

@fabwizard: Do you have a source for any of these claims? What markets and products does it not matter for? And according to whom does it work less as tech progresses? Pioneer advantage is still working just fine for high-tech companies like Apple, Netflix, and Tesla

@RadBartTaylor: To be fair, even without patent protection there is still incentive to develop new products, also known as the pioneer advantage. So it really not true to say there is no incentive, although almost certainly less than with patent protection

Tech Week 2023: Pole's New Vikkelä Ditches the Motor, Keeps the 190mm of Travel
For any nerds out there, most bike frames are built from 6061, this is built from 7075 which is nearly twice as strong. Its also generally un-weldable, hence the CNC machining and bonding. Cool stuff.
